Massachusetts Congressman Seth Moulton has jumped into the crowded race for the Democratic presidential nomination, presenting himself as a candidate of generational change. Moulton, a resident of Salem who represents the state's 6th Congressional District north of Boston, is serving his third term in Congress. He's also a U.S. Marines veteran. In the video, he puts his commitment to public service and moral values at the center of his long-shot bid for the White House.

Moulton has an impeccable resume that is matched by big political ambition. After graduating from Harvard University in 2001 with a Bachelor of Arts in physics, Moulton joined the U.S. Marines and served four tours in Iraq, and then went on to earn master's degrees in business and public policy at the Harvard Business School and Harvard's John F. Kennedy School of Government.
